    Instantaneous antidepressant effect of lateral habenula deep brain stimulation in rats studied with functional MRI

    Gen Li, Binshi Bo ... Xiaojie Duan
    Electrical stimulation at the lateral habenula causes an instantaneous remission of depressive symptoms in two rat models, with more medial stimulation sites exhibiting greater antidepressant effects than more lateral stimulation sites, as revealed by functional MRI studies.

    APOE expression and secretion are modulated by mitochondrial dysfunction

    Meghan E Wynne, Oluwaseun Ogunbona ... Victor Faundez
    Current models of Alzheimer's disease that put mitochondria as an endpoint of disease should be reconsidered because genetic defects affecting mitochondria by themselves can also regulate Alzheimer’s disease risk factor apolipoprotein E (APOE) expression and secretion.

    The nematode worm C. elegans chooses between bacterial foods as if maximizing economic utility

    Abraham Katzen, Hui-Kuan Chung ... Shawn R Lockery
    A worm with a nervous system of only 302 neurons satisfies the necessary and sufficient conditions for value-based decision making.

    Spatiotemporal neural dynamics of object recognition under uncertainty in humans

    Yuan-hao Wu, Ella Podvalny, Biyu J He
    Combining 7 Tesla fMRI and MEG data collected during a challenging visual recognition task revealed distinct neural representational formats in ventral visual and frontoparietal regions, and the emergence of recognition-related signals prior to category-related information.

    Mating activates neuroendocrine pathways signaling hunger in Drosophila females

    Meghan Laturney, Gabriella R Sterne, Kristin Scott
    Postmated increases in sucrose consumption in Drosophila melanogaster females is executed by a female specific circuit that alters neuroendocrine centers to promote hunger.

    The normalization model predicts responses in the human visual cortex during object-based attention

    Narges Doostani, Gholam-Ali Hossein-Zadeh, Maryam Vaziri-Pashkam
    A normalization model is shown to predict responses to multiple objects across changes in the attentional state in the visual cortex, providing evidence for the role of normalization as a fundamental operation in the human brain.

    Task-evoked metabolic demands of the posteromedial default mode network are shaped by dorsal attention and frontoparietal control networks

    Godber M Godbersen, Sebastian Klug ... Andreas Hahn
    In the human brain, default mode network BOLD deactivations can be accompanied by both increases and decreases in glucose metabolism, depending on the respective metabolic demands of task-positive cognitive control and attention networks.

    Local angiogenic interplay of Vegfc/d and Vegfa controls brain region-specific emergence of fenestrated capillaries

    Sweta Parab, Olivia A Card ... Ryota L Matsuoka
    Novel and common angiogenic mechanisms crucial for fenestrated brain capillary formation have been identified.

    Chronic exposure to odors at naturally occurring concentrations triggers limited plasticity in early stages of Drosophila olfactory processing

    Zhannetta V Gugel, Elizabeth G Maurais, Elizabeth J Hong
    Chronic stimulation with odors at naturally occurring concentrations only mildly impacts early stages of olfactory processing, suggesting a need to re-interpret prevailing models of how chronic odor exposure affects olfactory function.

    Oxytocin administration enhances pleasantness and neural responses to gentle stroking but not moderate pressure social touch by increasing peripheral concentrations

    Yuanshu Chen, Haochen Zou ... Keith M Kendrick
    A randomized placebo-controlled trial with behavioral, neuroimaging, and physiological measures reveals that oxytocin treatment facilitates pleasure and brain reward responses only to gentle stroking social touch by increasing peripheral blood concentrations.
